I did it yesterday. Rode 'Century for the Cure' out of Warren,NJ. I started biking a year ago(rode 4.8 miles on the bike path in Frenchtown,NJ on a rented bike) and set this goal for a century when I bought my road bike in the spring. It was a phenomal experience and I feel great today . Had lots of miles on the bike beforehand so only discomfort was my right bunion and seam in my shoe going at it(owee!) at the end. I'm still 'riding' high from it but SO not interested in hearing about it.
